Performance Analysis of Grid-Connected 10.6 kW (Commercial) Solar PV Power Generation System

Abstract

In this paper design aspects and performance of a rooftop grid-connected solar photovoltaic power plant (RTGCSPVPP) has been studied. The RTGCSPVPP is installed at Gauri Maternity Home Ramkrishna Puram Kota Rajasthan, India for supplying the energy to whole hospital building. It was observed under a certain period of time during May 2017. Power output and other parameters such as economic parameters which affect the feasibility of a PV plant as payback period, net present value, life cycle conversion efficiency, environmental related parameters as CO₂ mitigation and earned carbon credits were calculated. Total energy demand and monthly energy consumption of previous one year of the site was assessed and analyzed for base load calculation and design. The outcome shows the financial viability and possible reduction of burden on conventional energy sources. The grid-connectivity of PV plant made through a net-metering system which supplied energy to the grid when power generation is more than its demand and receives the energy during low power generation.
